Demo Questions

Question 1
An organization conducts research on the benefits of leveraging the Web Proxy feature of PAN-OS 11.0.
What are two benefits of using an explicit proxy method versus a transparent proxy method? (Choose two.)
  1. No client configuration is required for explicit proxy, which simplifies the deployment complexity.
  2. Explicit proxy supports interception of traffic using non-standard HTTPS ports.
  3. It supports the X-Authenticated-User (XAU) header, which contains the authenticated username in the outgoing request.
  4. Explicit proxy allows for easier troubleshooting, since the client browser is aware of the existence of the proxy.
Correct answer: C, D
Question 2
An engineer is configuring a firewall with three interfaces:
  • MGT connects to a switch with internet access.
  • Ethernet1/1 connects to an edge router.
  • Ethernet1/2 connects to a virtualization network.
The engineer needs to configure dynamic updates to use a dataplane interface for internet traffic.
What should be configured in Setup > Services > Service Route Configuration to allow this traffic?
  1. Set DNS and Palo Alto Networks Services to use the MGT source interface.
  2. Set DNS and Palo Alto Networks Services to use the ethernet1/1 source interface.
  3. Set DNS and Palo Alto Networks Services to use the ethernet1/2 source interface.
  4. Set DDNS and Palo Alto Networks Services to use the MGT source interface.
Correct answer: B
Question 3
An engineer is reviewing the following high availability (HA) settings to understand a recent HA failover event.
Which timer determines the frequency between packets sent to verify that the HA functionality on the other HA firewall is operational?
  1. Hello Interval
  2. Monitor Fail Hold Up Time
  3. Heartbeat Interval
  4. Promotion Hold Time
Correct answer: A
Question 4
Which new PAN-OS 11.0 feature supports IPv6 traffic?
  1. OSPF
  2. IKEv1
  3. DHCP Server
  4. DHCPv6 Client with Prefix Delegation

Question 5
After importing a pre-configured firewall configuration to Panorama, what step is required to ensure a commit/push is successful without duplicating local configurations?
  1. Ensure Force Template Values is checked when pushing configuration.
  2. Push the Template first, then push Device Group to the newly managed firewall.
  3. Push the Device Group first, then push Template to the newly managed firewall.
  4. Perform the Export or push Device Config Bundle to the newly managed firewall.
Correct answer: D
Question 6
After implementing a new NGFW, a firewall engineer sees a VoIP traffic issue going through the firewall. After troubleshooting, the engineer finds that the firewall performs NAT on the voice packets payload and opens dynamic pinholes for media ports.
What can the engineer do to solve the VoIP traffic issue?
  1. Disable ALG under H.323 application
  2. Increase the TCP timeout under H.323 application
  3. Increase the TCP timeout under SIP application
  4. Disable ALG under SIP application
Correct answer: D
Question 7

Which two types of certificates are used to decrypt the traffic? (Choose two.)
  1. Device certificate
  2. Subordinate CA from the administrator’s own PKI infrastructure
  3. Self-signed root CA
  4. External CA certificate
Correct answer: B, C

  1. LDAP
  2. Log Ingestion
  3. HTTP
  4. Log Forwarding
Correct answer: C, D
Question 9
What is the PAN-OS NPTv6 feature based on RFC 6296 used for?
  1. Application port number translation
  2. IPv6-to-IPv6 network prefix translation
  3. Stateful translation to provide better security
  4. IPv6-to-IPv6 host portion translation
Correct answer: B
Question 10
Where can a service route be configured for a specific destination IP?
  1. Use Network > Virtual Routers, select the Virtual Router > Static Routes > IPv4
  2. Use Device > Setup > Services > Services
  3. Use Device > Setup > Services > Service Route Configuration > Customize > IPv4
  4. Use Device > Setup > Services > Service Route Configuration > Customize > Destination
